What affects the response time of the monitor

Response time

A parameter that is almost always specified. For those who love games, this is one of the main parameters of the screen. The response time determines how clear the picture will be in dynamic scenes. It manifests itself, for example, in the form of trails that stretch behind the elements of the image that are rapidly moving across the screen. The shorter the response time, the better.

affects, response, time, monitor

This parameter depends on the manufacturing technology used in a particular display matrix. So, the most “high-speed”. TN screens, and this is almost the only (if not taking into account the cost) reason that this type of displays has not “died” yet. IPS. slower, and VA are in between these types of matrices in terms of response speed.

If the screen is chosen for office work, for surfing the Internet, watching videos, working with images, then this parameter is not very important. Now, if you are a true fan of virtual battles, then a screen with a minimum response time is a must. And here you can even put up with the worst color rendering, unimportant viewing angles of TN matrices. Their response time is the shortest.


This parameter reflects the ratio of the brightness level of white to black. Usually it is specified as a ratio, for example 1000: 1. As with brightness, the higher the value, the better. The image will be more natural.

The contrast depends on the technology used to manufacture the matrix. So, IPS screens are inferior in this parameter to screens made using VA technology, not to mention OLED, quantum dots, etc.

Conventionally, we can assume that screens with a contrast ratio of 500: 1 or less can be classified as mediocre. Better to target values ​​of 1000: 1 and higher. Especially if in your work you have to deal with image editing, colorization, etc.

Screen surface type

Looking at the monitors themselves, you can see that some of them are glossy, the surface is shiny, has a mirror effect. Other screens, on the contrary, reflect practically nothing and deal well with glare. There are two types of surface. glossy and matte. You can also find semi-gloss models, but these are attempts to combine the advantages of both types, reducing the disadvantages inherent in each of them.

So, the undoubted advantages of gloss include better brightness and contrast, better color reproduction, the image is perceived more clearly. For those who work with images, it is better to prefer this type of Honor.

There are also disadvantages to glossy screens. These are, of course, glare and reflections of bright objects. lamps, bright windows, etc. This can tire the eyes. Such screens are poorly suited for laptops that are often used outdoors in bright sunlight. Another unpleasant feature is the unauthorized collection of fingerprints on screens with such a surface, as well as other contaminants. It is better not to poke your fingers at the screen, so as not to constantly rub off the remaining traces.

Matte screens “by definition” do not glare, behave better in bright light, but this is achieved due to the deterioration of contrast and color rendition. There is one more drawback typical for matte screens, this is the “crystal effect”. It manifests itself in the fact that the displayed point has no clear boundaries, but may have some uneven edges with different shades.

How noticeable it is depends on the features of your vision. Someone such “crystals” are literally striking, while others do not notice them. However, image clarity suffers from this.

Matrix type

This is almost always indicated. The main types of matrices currently used are TN, IPS, VA and their modifications. details can be found in my other material.

15 Monitor Features You Should Know Before You Buy

The choice of any computer or any component begins with determining the criteria, which in this case are technical characteristics. Agree, when buying, for example, a monitor, there is little definition of “to show well”, you need to know what size the display is needed, with what resolution, how it will be connected, for what purposes it will be used (for games, office work). To answer these and a number of other questions, you need to know what characteristics of monitors are, which are important, which are not very much, and what is usually silent in official specifications.


I think such characteristics as weight, size, type of power supply (built-in or remote), power consumption during operation and in idle, built-in speakers, wall mounting, etc. is not something complicated and incomprehensible. Therefore, I will not describe them.

Monitor specifications

Let’s briefly list the characteristics that each monitor possesses, without exception. Let’s make a small guide with a brief description of what it is, how important the parameter is, what it affects and what values ​​it is desirable to strive for. Unfortunately, not all characteristics can be found in the descriptions of the monitor, be it a laptop screen or a display for a stationary PC. At the same time, among those parameters that are usually hidden, there are very interesting ones that can affect the image quality.

Color depth

Another parameter that is difficult to find in the specifications for a particular monitor, but such information is in the characteristics of the matrix used. In simpler terms, it is the number of displayed colors. You can often find that the monitor displays 16.7 million colors. This is the most common value for this parameter. The problem is that this can be achieved in different ways.

Let me remind you that any color is formed from three main ones. red, blue, green. Accordingly, the matrix of the monitor has a certain bit depth for each such color, measured in bits. If there are 8 bits for each color, then we get 256 shades of each color, which in combination gives 16.7 million colors. Everything is fine, the monitor shows excellent, you can take.

What if each color is not encoded with 8 bits? In cheap displays, 6-bit matrices are often used, but in addition the abbreviation “FRC” is also indicated. What do these letters mean??

First you need to have Honor, that with 6-bit color coding, you can get 262K colors. How do you get the final 16 million? Exactly due to FRC technology (Frame rate control).

The bottom line is to get the “missing” halftones by showing an intermediate frame with two other colors, which ultimately give those shades that are not available for a 6-bit matrix. In fact, we have one more flicker.

Is having an FRC bad? Again, a lot depends on the tasks that are performed on the monitor and on the peculiarities of vision. Someone does not notice FRC, someone on the contrary, it is annoying. And purely subjective, if you have to work with color, it would be better to have a monitor with an “honest” 8-bit matrix.

For professionals, monitors are available with a 10-bit matrix, which allows you to display more than a billion colors. I think it is not necessary to say that the cost of such monitors is not the smallest, and for office / home / gaming use an 8-bit monitor or even 6-bit FRC is quite suitable, if flickering is not noticeable and high requirements are not imposed on the screen.

What is the response time of a computer monitor

In computer technology, a response interval refers to the time it takes for a system to respond to changed data. Monitor response time is the amount of time it takes for a pixel to change its color. Globally, this is the time that elapses between the arrival of the updated signal to the monitor and its display by the matrix. Latency is so low that it is measured in milliseconds.

In gameplay, the response of the monitor can be safely added to the network latency. Let’s illustrate this with an example: in an online shooter, the player appears from behind cover. The time after which the opposing player will notice this can be calculated by the sum of the following factors:

  • Ping the player who made the move
  • Server latency
  • Ping an opposing player
  • Latency of the opponent’s video card
  • Monitor response time

Of course, each factor individually is minimal and elusive to the eye. However, the combination of these time periods may be sufficient to gain a tactical advantage in a game (especially in a dynamic game).

What are the disadvantages of fast response

As we have already found out, the response time of the monitor gives a boost to the user’s performance in shooters and other video games. However, perfect monitors do not exist, and when the balance is shifted towards the acceleration of the vertical scan, other specifications will suffer. First of all, these are saturation and color rendition. The process of displaying colors correctly is quite complicated, so it takes a certain amount of time (which becomes a delay).

To speed up the color change process, a number of developers take the simplest way. they reduce the number of data processing steps. “Under the knife” are technologies that reduce eye strain (Flicker-free, etc.), color filters, accurate color correction and other usefulness. Therefore, a monitor tailored for gaming is unlikely to be suitable for designers, photographers and other professionals for whom color reproduction is at the top of the list of priorities.

How to change the response time in the monitor

The display, like any other technique, has a number of possibilities for improvement. Unfortunately, however, monitor response times are not included in this list. This parameter only affects hardware, and therefore cannot be improved. Only screen replacement will help.

However, it is still possible to improve the display for gaming. To do this, you need to change another important game parameter. the refresh rate of the matrix. This can be achieved programmatically through the Windows OS. The process of improving the refresh rate is called monitor overclocking. But you can forget about the desire to change the response time of the monitor. if this parameter is critical, it is easier to immediately start looking for a new device.

Monitor response time for gaming

Games, especially multiplayer games, place serious demands on responsiveness. The response time of the monitor for gaming should be no more than 5 ms, but even this parameter is considered insufficient. The best gaming displays are 1ms. Timely, with an accuracy of a split second, to see the danger and react to it is the key to victory in any dynamic game. And it’s not just about shooters. RPGs, soccer simulations and racing. in any of the above genres, responsiveness matters a lot. The presence of a fast game screen is comparable to professional sports equipment: without directly improving the player’s skills, it becomes a serious help in achieving success.

Another response-related characteristic is the refresh rate of the matrix. The higher this parameter, the smoother the picture is. The frequency value does not directly affect the player’s efficiency, but there is an indirect effect. A twitching picture leads to eye fatigue. By concentrating on his own condition, the player will be unable to react to events in a timely manner. In addition, for some, jerking the video is annoying, which also reduces the effectiveness of the game.

BtB or BWB

The so-called “cinematic response”. The method allows you to make sure that the image does not leave a “tail” after an abrupt stop. This method makes it possible to simultaneously estimate the frequency of the matrix update.

What affects

At the beginning of the article, it was briefly described what the matrix response is and how it works. Let us recall the example that was given. The display delay is summed up not only with the processing time on the PC, but also with the ping of the Internet connection. Everything seems to be clear, but this parameter has its own subtleties. Later in the article, I will show the importance of latency for games, the possible negative aspects that can arise from low latency, and also how the response parameter can be influenced.

Monitor response time

Video game technology must meet specific requirements. Unlike other tasks and processes, most video games are focused on the speed of decision making and the player’s reaction. This is especially true of online games in which people compete with each other. As in any other sport, it is not only the skills of e-sportsmen that play a role, but also the “sports equipment”. First of all, this is a powerful processor, video card and RAM. However, do not forget about another component of a successful game. displaying a picture. Many people are familiar with the term “ping”. the time interval during which data is transferred from a PC to a server or an opponent’s computer. However, there is one more latency factor that can and should be influenced. This is a parameter such as the response time of the monitor.

What is monitor response time and why it matters?

When you buy a new monitor, you will have a lot of technical specifications. And while things like screen size and resolution are pretty obvious, there is another important factor: response time. This is how it works.

Response time is the time it takes for your monitor to switch from one color to another. This is usually measured in terms of going from black to white back to black, in milliseconds. Typical LCD response times are less than ten milliseconds (10ms) and some are just one millisecond.

The exact method for measuring this statistic is not consistent: some manufacturers express it in terms of an LCD panel going from black to white, or black to white to black, or more often from gray to gray. full spectrum, but starting and ending with subtler, more complex grayscale values. In all cases, lower response times are better because they reduce image problems such as blurring or ghosting.

Response time should not be confused with monitor refresh rate. They sound the same, but the refresh rate is the number of times the screen displays a new image every second, expressed in hertz. Most monitors use 60Hz refresh rates, although some go higher, and the higher the better. On the contrary, the shorter the response time, the better.

Why fast response times are important to you?

Most computer users are not even aware of the response time of their monitor or screen, because in most cases it doesn’t matter. For surfing the web, writing emails or Word documents, or editing photos, the delay in switching screen colors is so long you won’t even notice. Even video on modern computer monitors and televisions usually does not have enough latency for the viewer to notice.

Games are an exception. For gamers, every millisecond matters. the difference between winning and losing a combat match, hitting a sniper from a long distance, or even getting that perfect line in a racing game can really be one millisecond. So for gamers looking for every possible competitive edge, the low refresh rate of 1 to 5 milliseconds is well worth the investment in a more expensive gaming-focused monitor.

What types of monitors are the fastest?

For your laptop or phone, you generally have no choice for poor on-screen response times, although there are exceptions. But if you’re buying a new monitor for your gaming computer, you’ll want the fastest panel you can afford.

At the time of this writing, there are three different types of LCD panels that cover 99% of monitors sold today.

  • TN (Twisted Nematic) display panels: Inexpensive, but usually have poor color gamut. They are some of the fastest on the market in terms of response times, and gaming monitors often opt for less colored TN panels to be faster.
  • In-Plane Switching (IPS) display panels: expensive and more accurate colors, IPS monitors are appreciated by graphic designers, photographers, video editors and anyone who cares about accurate colors. They have faster response times than TN panels, so they are rarely sold as “gaming” monitors.
  • VA (Vertical Alignment) Screen Panels: A new design that attempts to combine fast TN response times with more accurate, vibrant IPS color. It’s in the middle, but many gaming monitors are now made with VA panels that only have a one-millisecond refresh rate.

What are the disadvantages of fast response?

To improve response times, gaming monitors often ditch the more complex image processing that takes place between signals from the computer. This includes color correcting parts of the monitor itself, increased brightness, blue light filters to reduce eye strain, and similar features. If you go for a gaming monitor and set it to the fastest response time possible, you will likely see a decrease in brightness and dimmer colors.

Should you buy a monitor with fast response time??

Is it worth it? Not very good for many games. If you are playing in single player mode and the only opponent you have to face is the computer, then this random blur or ghost image may not be worth the aesthetic blow you take to buy a gaming monitor and set it to the fastest mode. casual games like Minecraft just don’t benefit from such ultra-low image latency, even when played online.

Speaking of online: if the connection to your multiplayer game is poor, the time your computer sends information to the game server and returns information will probably be much longer than your response time anyway. Even on a “slow” monitor with a response time of 10ms, if your game has a 100ms ping to the server (one tenth of a second), image lag issues will not be the deciding factor in your victory.

But if you have a fast internet connection and often play fast-paced multiplayer games like Fortnite, Overwatch, Rocket League, or Street Fighter, you’ll want to use every last millisecond on your side. The same is true for game consoles and TVs (many of which have a “game mode” that will reduce response times) and remains true if you connect your console to a computer monitor.

Is it a lot or a little, and what is the best monitor response time?

  • If the time is long, then with abrupt changes in the scene artifacts will appear. where the already black matrix still shows white. Or an object is displayed that has already disappeared from the camera’s field of view.
  • When fuzzy pictures are shown to the human eye, vision fatigue increases, headaches may appear, and fatigue may increase. This is due to the visual tract. the brain constantly interpolates information from the retina, and the eye itself is busy with a continuous change of focus.
READ  Monitor Response Time Which Is Better

It turns out that less is better. Especially if you have to spend most of your time at the computer. The older generation remembers how hard it was to sit in front of the CRT for an eight-hour workday. and after all, they provided 60 Hz or more.

Response time in a monitor for gaming

If the main purpose of the computer is games, then it is worth choosing a monitor with the lowest response time. In dynamic shooters, even a tenth of a second can decide the outcome of a battle. Therefore, the recommended monitor response time for games is no more than 8 ms. This value provides a frame rate of 125 Hz, and will be absolutely sufficient for any toy.

At the closest next value of 16ms, motion blur will be observed in hard mixes. These statements are true if the declared time was measured by BWB, but the companies of cunning can write both 2 ms and 1 ms. Our recommendation remains the same. the less the better. Based on this approach, let’s say that the response time of the monitor for games should be at least 2 ms, as 2ms GtG approximately corresponds to 16 ms BWB.

How to find out and check the response time?

Although they are milliseconds in Africa, milliseconds, but surely many have come across the fact that different monitors with the same performance form an image of different quality. This situation has arisen due to different methods for determining the matrix reaction. And what method of measurement was used by the manufacturer in each specific case is hardly possible to find out.

There are three main methods for measuring monitor response:

  • BWB, also known as BtB, is an abbreviation of the English phrase “Black to Back” and “Black-White-Black”. Shows the time it takes for a pixel to switch from black to white and back to black. The most honest indicator.
  • BtW. stands for “Black to White”. Switching on from inactive state to 100% luminosity.
  • GTG is short for “Gray to Gray”. How many points does it take to change the gray brightness from ninety percent to ten. Usually in the order of 1-2 ms.

And it turns out that checking the response time of the monitor using the third method will show a much better and attractive result for the consumer than checking the second. But you will not find fault. they will write that 2 ms and so it will be. Yes, only in fact on the monitor and artifacts climb, and the picture goes like a train. And all from the fact that the true state of affairs is shown only by the BWB method. the first method, it is he who testifies to the time required for a pixel for a full working cycle in all possible states.

Unfortunately, the documentation available to consumers does not clarify the picture and what is meant by, for example, 8 ms is difficult to understand. Will it fit, will it work comfortably?

For laboratory research, a rather complex hardware and software complex is used, which not every workshop has. But what if you want to check the manufacturer?

Checking the response time of the monitor at home is carried out by the TFT Monitor Test program. Selecting the test icon in the software menu and specifying the native screen resolution, a picture with a rectangle scurrying back and forth is displayed on the display. At the same time, the programmlin will proudly show the measured time!

We used version 1.52, checked several displays and concluded that the program shows something, and even in milliseconds. over, the monitor of the worst quality showed the worst results. But since the time of extinction and ignition of pixels is recorded only by a photosensor, which did not exist, a purely software method can be recommended for a subjective comparative assessment. what the program measures is understandable only to its developers.

A much more visual empirical test will be the “White square” mode in the TFT Monitor Test. a white square moves across the screen, and the task of the tester is to observe the train from this geometric figure. The longer the loop, the more time it takes to switch the matrix and the worse its properties.

That’s all you can do to solve the “How to check the monitor response time” problem. We will not describe the methods using cameras and calibration tables, but we will consider them another time. this will take another couple of days. A full check can only be performed by a specialized organization with an appropriate technical base.

What does response time affect??

So, the principle of LCD operation is that the matrix cells change their brightness under the influence of a control signal, in other words, they are switched. And this switching speed or response time just determines the maximum speed of changing the picture on the display.

It is translated into the usual hertz by the formula f = 1 / t. That is, in order to obtain the required 25 Hz, it is required to provide the pixels with a speed of 40 ms and 33 ms for 30 Hz.

What is the response time of a computer monitor?

In dry scientific terms, the response time of liquid crystal monitors is the shortest time it takes for a pixel to change the brightness of the glow and is measured in milliseconds. (Ms)

It would seem that everything is simple and understandable, but if you consider the issue in detail, it turns out that these numbers hide several secrets.

The days of warm and tube CRT monitors with honest frame scan hertz and RGB color have already passed. Then everything was clear. 100 Hz is good, and 120 Hz is even better. Each user knew that these numbers show. the picture on the screen is updated or blinked so many times per second. For comfortable viewing of dynamically changing scenes (for example, movies), it was recommended to use a frame rate of 25 for TV and 30 Hz for digital video. The basis was the assertion of medicine that human vision perceives an image as continuous if it blinks at least twenty-five times per second.

But technologies have evolved, and the CRT (cathode ray tube) was taken over by liquid crystal panels, which are also called LCD, TFT, LCD. Although production technologies differ, but in this article we will not focus on the little things, we will tell you about the differences between TFT and LCD another time.

What is monitor response time and what does it mean?

Hello dear readers. Monitor response time what is it and do we really want to know the terrible truth? If so, read today’s post. In it, I will analyze this characteristic in detail, and, as always, I will give some valuable advice on choosing the device of interest.

Subscribe to the newsletter not to miss new interesting posts!

A bit of theory

With warm and tube CRT monitors, everything was simpler: the refresh rate of the frame scan made it clear: 60 Hz is good, and 120 and 144 are twice as good. In fact, this value shows how many times the picture on the screen will be updated per minute.

However, technologies have evolved, and LCD panels have replaced the usual picture tubes. Several parameters have appeared that differ for different types of matrices. color rendition, dynamic contrast, viewing angle, etc. It is logical that the response time may also differ.

What does this characteristic mean? It would seem that there is nothing special. just the time in milliseconds it takes a pixel to change the brightness of the glow. Yes, it is precisely in milliseconds that this is measured. the engineers have become so meticulous in bringing such matrices to perfection.

What does this mean in practical terms

The longer the response time, the longer the monitor will respond to an already changed picture. This is completely unimportant, for example, when working with a text document or spreadsheet: most users do not print so much faster to notice that the monitor is “dull”.

The parameter is almost not taken into account, and when working with graphics and processing, it is already more important here that the monitor displays the full palette of colors and distorts them as little as possible.

However, response time is very important for games, as well as when watching blockbusters with chases and gunfights, where scenes follow each other at a breakneck speed.

I want to note that in the case of games, we are not talking about shooters and other dynamic fun. even a primitive casual game from the category of “three in a row” suggests that the picture, albeit in some areas of the monitor, will constantly change, and quite quickly.

Throw in all sorts of effects and animations that the developers add, and you have a complete picture. Why animation? With such competition in a niche in a game where three blocks of the same color simply disappear, almost no one will play, I guarantee.

It is necessary that lightning strikes, thunderclaps, a virtual assistant praising the wise master from the side, everything shone and sparkled everywhere, and at the end of the round, a cute beauty sent air kisses to the hero.

And since we started the topic of games, I’ll tell you about the complete opposite. And I’d rather give you a riddle (or give you a quick wits test, whatever you like): in what situation in a fast-paced online shooter does the picture on the screen stay the same for a long time? I am waiting for the correct answers in the comments.

READ  What to do if there is a dead pixel on the monitor

But we got a little distracted. A natural question may arise. is there a big difference between 1 ms and 4 ms? It would seem not. Let’s say that not every stopwatch will record such a value, except that an electronic.

But the human eye, one of the most perfect creations of Mother Nature (after the eye of an eagle, of course), sees such a difference perfectly. over, the eye has time to react and with a shorter response time.

Advanced gamers have time to react and the brain, and professional e-sportsmen also have time to send the appropriate command to the limbs. Those who, at the same time, have time to react and manage to hit the right buttons, are usually at the top of the rating in some championship.

Or, for example, in the leaderboard of a PVP-oriented online game, where the victory is influenced by the “straightness of the hands”, and not the amount of money invested in equipment.

What response time is considered acceptable for games:

This method of measurement is very popular among marketers and sales departments: even the cheapest matrix can show a decent result in this case.

accurate data can be obtained by measuring using the BWB method, that is, “black to black”. the time during which a pixel switches from black to white and back to black. Sometimes BtW is also used. switching time from absolutely black to full luminance of a pixel.

As you might have guessed, almost all monitor manufacturers quote response times as measured by the GtG method. For measurements, a complex hardware and software complex is used, which is not available in every service center.

At home, you can check how much the manufacturer deceived us using the TFT Monitor Test utility. There is nothing complicated: the program runs multi-colored geometric shapes across the screen and after measurements shows, oddly enough, a completely plausible result.

And in conclusion I want to say that the response time of the matrix cannot be changed. neither in the settings, nor in any other way.

Unless you are a great magician and sorcerer who knows how to change the physical properties of material objects. But in this case, I suppose you have slightly different interests, and you don’t really need a monitor, right?

And in conclusion, I want to recommend the correct and not expensive gaming device with a response time of 2 ms. Samsung S24D300H (300HSI). Share this post on social media if you find it helpful. Until!

PS: One of the correct answers: when you play as a sniper and you camp in ambush.

From pressing to displaying a picture on the screen

The total time it takes for the action to appear on the screen is input lag. The user presses a key or button on the keyboard or controller and then waits for the corresponding action on the gaming monitor or TV. The time it takes to show a picture on the screen that corresponds to the action done and there is a delay in input.

Input lag depends on many factors. From a controller, mouse or keyboard, the signal goes to your computer or console. If you are using wireless input devices, this will take much longer than the wired versions. Then your computer or console will take time to process the data you provided, and then. to send graphic information via cable to your display. Typically, HDMI and DisplayPort have the same signal rate. the speed of light, so cables are not a major issue in terms of latency. As soon as the monitor has received the signal, it starts updating the picture on the screen. Thus, the response time of the monitor affects the overall latency, as we mentioned above. The time it takes for the monitor to receive the signal, process it, and then change the pixels to display the visual effects obviously increases the overall latency obviously.

It’s important to note that any image processing done on your monitor will increase latency. Even if the base response time is 1ms, but if you add HDR, dynamic brightness / contrast, edge sharpening, local dimming and the like to this, then the latency increases. Therefore, we recommend using PC Mode or Game Mode for gaming. They turn off most of the image processing to reduce the response time on the monitor.

How input latency is measured?

Input latency, like response time, is measured in milliseconds. But the order of the numbers will be much larger. Really good monitors like the BenQ EL2870U, 4K EW3270U monitor, and 144Hz EX2780Q gaming monitor have 9-10ms latency based on third party reviews, but average hovers somewhere between 15ms and 22ms for typical gaming and gaming monitors. systems.

With such latency indicators, you will not experience any problems with the picture. Only if the latency is greater than 40ms will you experience a sync problem. It’s basically impossible to play on monitors with a total latency of 50 ms.

What is input lag and response time: what’s the difference between them?

If you’re looking for a new gaming monitor, be it 60Hz, 144Hz, or even 240Hz, you should also pay attention to two very important monitor characteristics. input lag and response time, among other things. While most potential gaming monitor buyers know what refresh rate (or frame rate) is, many don’t understand the difference between response time and input lag.

In addition, response times are listed on the packaging of each gaming monitor in the specifications section, and input lag rarely appears. This is because manufacturers can easily calculate and test monitor response times in the factory, but input lag is a much more complex metric. Many factors affecting input lag have nothing to do with the monitor or the manufacturing process of the display, so manufacturers simply cannot have information about the input lag in each specific case.

Why do many people confuse these concepts?

The response time is a fraction of the total input lag. This likely explains why so many people misunderstand that these two specifications describe different but closely related aspects of a gaming monitor. Another reason is that both are speed characteristics and are often mentioned when it comes to gaming monitors and their optimal performance. Often cited in the same sentence, response times and input lag are sometimes mixed together.

Both characteristics tell us about the speed of the gaming monitor, the speed at which images change on the display, and how they react to your actions. In this case, the response time completely depends on the monitor itself, while the input delay includes the entire process from pressing a button until the corresponding picture appears on the screen.

Response time

Response time is the amount of time that the monitor or panel changes the properties of each pixel. The response time tells us how long it will take for the monitor to change the color of a pixel, for example, from red to green. The faster the pixels are refreshed, the faster and smoother the screen refreshes

Monitor manufacturers usually use GtG response times. from gray to gray. Switching between grayscale is much faster than switching between RGB primary colors and this number is an excellent indicator of monitor speed. GtG response times of less than 5ms are quite acceptable for gaming, although the best option is, of course, 1ms.

Imagine you are playing a first-person game and decide to turn left, down an alley. Your monitor is receiving data from your PC or console and should update the image and display the new image. A 5ms monitor does it five times slower than a 1ms screen. Of course, we are talking about milliseconds, so the difference may not be as noticeable to the naked eye. But slow response times will contribute to overall input lag.

Different types of gaming monitor panels have different response times. TN panels have the fastest response, so they are best suited for competitive gaming. Basically, all monitors with TN panel run for 1ms, so this is the only panel type that is capable of supporting refresh rates up to 240Hz. VA and IPS panels typically have response times between 2ms and 5ms, but provide excellent colors and viewing angles. If you want to know more about different panel technologies, then this article is for you.

TN panels perform image processing with the fewest pixels of the three main panel types. This explains their high speed. VA and IPS panels have been designed for excellent color reproduction, so they require more pixel processing and response times.

Also, it’s important to note that the larger the screen, the slower the response time will be. Likewise, the higher the resolution, the slower the response. Larger panel sizes require signals to travel more distance, and higher resolution means more pixels to update. With advances in technology, the difference between 24 “and 32” monitors has narrowed to almost zero, and 4K displays are as fast as 1080p monitors.

Response time is a characteristic of the monitor and helps to understand how fast the panel itself is performing. Total latency is a much more useful number because it includes response times and illustrates a real gaming experience.
